Russia claims it may have killed top ISIS leader in an airstrike in Syria

Russia's Defense Ministry said Friday it is investigating reports that ISIS leader Abu Bakr al-Baghdadi was killed in one of its airstrikes in Syria last month.

The Russian Defense Ministry said Abu Bakr al-Baghdadi was killed in a Russian strike in late May along with other senior group commanders.

There had been previous reports of al-Baghdadi being killed but they did not turn out to be true.

"According to information, which is being verified via different channels, the meeting was also attended by the (ISIS) leader Ibrahim Abu Bakr al-Baghdadi, who was eliminated in the strike," the ministry said, according to the TASS report in English.
